SPECIFICATION forming part of Letters IEatent No. 554,367, dated February 11, 1896. Application filed July 6,1895. Serial No. 555,096. (No model.)

To all whom it may concern.-

Be it known that I, JAMES B. J ARMIN, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Corn-Planters and I do declare the following to be a full, clear, and exact description of the invention,-such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements upon that class of corn-planters an example of which forms the subject-matter of Letters Patent granted to me May 2, 1893, and numbered 496,415, and yet which is equally applicable to corn-planters generally,

and it has for its object, primarily, to do away with the old wire check to effect the dropping of the corn at certain intervals in forming the hills; also to provide for the eflicient working of the machine in uneven or other ground, and the automatic operation thereof, or its operation from the seat of the attendant or driver, while it is readily applied or attached for use to any machine and is easy of manipulation and simple in construction, and to these ends the invention consists of certain features which will be first described hereinafter and then pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my invention. Fig. 2 is .a transverse section of same on line a: 00 of Fig. 1. Fig. 3 is a transverse section of the same on line' y of Fig. 1. Fig. 4 is an enlarged detail view of the seed or corn dropping 1nechanism. Fig. 5 is a similar sectional View of said mechanism. Fig. 6 is a sectional elevation of details.

In the embodiment of my invention or attachment I mount the shaft A of the marking or propelling wheels B in upward and rearward curved or inclined arms or standards 0, secured at their lower en ds to an equalizer-bar D, at its ends bolted to the inner or rear end of the tongue or draft-pole a. The shaft A has its journals orbearings b arranged in slots 0 in the arms or standards C, so as to be vertically movable, and is held in its normal position and the wheels B to their work by the pressure or action of springs E, held in position upon said shaft, among other ways, by rods cl passing through plates 6 resting upon marking or propelling wheels will by reason of the aforesaid arrangement of parts be permitted to alike accommodate themselves and thus provide for efficiency of operation and prevent the breaking or impairment of the same. Each alternate arm or spoke of the propelling-wheels B is provided with a preferably incline-edged plate or marking device f, adapted to mark the ground opposite the formation of the hills of corn by the dropping of the seed-corn from the seed-boxes, as well understood, and at such a distance therefrom as to indicate the line of travel or traversing of the field by the machine upon its return movement, one wheel traveling in one row of the previously-produced marks, and whereby the hills of corn are formed opposite the large marks-those produced by the plates or marking devices fand in straight lines both ways.

H H are the seed or corn boxes, suitably mounted upon the machine frame, and which are adapted in connection with the usual slide-bar g, when operated as presently described, to permit of the dropping of the corn or seed in the formation of the same into hills.

Upon the shaft A is secured a sprocket or rag wheel h, and upon a short shaft 1', suitably supported and journaled upon the machine frame, is secured a small pinion j, which wheel and pinion are compassed by a chain belt 70, to transmit motion from said shaft to said pinion. The shaft 2' has also fixed on it a mutilated pinion Z, having a certain number of teeth which are adapted to engage with the teeth of a bevel-pinion m, the number of the teeth on which is twice that of the number of teeth on pinion Z, and upon the pivot-stud of the pinion m is mounted a link m, which carries a stud or pin m which is pivotally connected with one end of a rod or link m whose opposite end carries a stud or pin m pivotally connected with the slidebar g.

At the first interval of engagement of the pinions l 'm the sernirotation of the link m causes the bar 9 to be pushed or carried in one direction, and at the other interval of engagement of said pinions [m the completion of the revolution of the link m causes the.

bar 9 to be carried in the opposite direction. Thus the dropping of the seed or corn is effected at the required intervals.

The equalizer-bar D, to which are secured the arms or standards 0, through which passes the marker-wheel shaft A, and to which equalizer-bar is bolted the draft -pole or tongue, is held at its ends in guides 01, suitably secured in position, andrests against springs 0, arranged upon bolts 19, passing through bearings p, carried by the connecting-piece between the forward ends of the usual runner-like portions of the seed-conductors q, whereby the draft and resistance are equally distributed throughout and the operation of the machine thus rendered more uniform and efficient'andeasy.

The rock-shaft G, to which are connected I the jointed bars F, connected to the springs E, pressing-upon the marker-wheel shaft A, is connected or linked to the hand-lever 1, preferably bymeans of an arm 4", removablyheld upon the rock-shaft G, and a link 5, adjustably connected to said'arm and to said hand-lever, whereby the aforesaid parts are brought under the control of-the operator to vary or increase or diminish the tension of the-springs upon the marking-wheel shaft to accordingly regulate the action of the marking-wheels upon the ground, and to provide for throwing the machine out of operation orinto operation, as required.

A are the usual supporting-wheelssuitably mounted in the machine-frame.

Having thus fully described, my invention, 40

what I claim, and desire to secure by Letters Patent, is-

1. The combination with the arms or standards through which passes the shaft bearing the marking-wheels of the equalizer-bar connected to the draft-pole or bar, and the springs acting upon said equalizer-bar, substantially as set forth.

2. The combination, with the marking wheel shaft, of the forcing orholding springs acting upon said shaft, the articulated or jointed bars connected to said springs, and a rock-shaft, and the hand-lever, substantially as specified,

3. The combination with arms or standards through which passes the shaft of the marking-wheels, of the equalizer-bar secured to the draft-bar, the guides through which passes the equalizer-bar, and the pulling-springs against which rests said equalizer-bar,, substantially as described.

4. The combination with the markingwheels and their horizontal shaft, of a sprocket-Wheel on said shaft, a second horizontal shaft, a pinion journaled on the latter shaft and geared-to the sprocket-wheel, a mutilated pinion on said second shaft, a bevel-pinion carried by a vertical stud, a link on the latter and having a pin, and a second link pivotally connected with the said pin, a pin on the second link, and the seed-slide bar to which the latter pin is pivotally connected.

In testimony, whereof I affix my signature in presence of two witnesses.
